The star hopping detail didn't record, but normally I start from very bright and
well know star to ensure right position. for M10 & other globular clusters in Orphiucus
,started from Antares in Scorpius (sky atlas p.22) hop to Sabik in Phiuchus and continue
with sky atlas p.15, hop to star 20, 13, 23 & 30. M10 locates at right angle corner of
triangle comprise of 23, 30 & M10. Located M10 at center of finder scope, it can't see
in finder, goto eyepiece and did some find adjust, M10 appeared as faint,round & small
can't resolve any stars. Hopping to M10, M12, M14 & M107 wasn't so difficult, I found all
in one night.
